Abstract: PURPOSE:To control the movement of an original scanning unit in a short time according to desired variable magnification by determining the section of a common-usable pattern in a control pattern memory according to driving control applied to a stepping motor. CONSTITUTION:When a signal 15 from an operation display circuit 10 which indicates the specification of operation or a signal 14 from a processing control circuit board which commands the start of scanning is inputted, a CPU4 sends out a signal 16 from a ROM5 or RAM6 to a pulse generating circuit 8 as determined frequency data on pulses to be generated. Then, control pulses 18 are supplied from the circuit 8 to a motor driver circuit 2 through a driver 11a with a gate signal 17 and a control signal 13 is supplied to the circuit 2 through a driver 11b. The circuit 2 supplies driving pulses 2a to the stepping motor to control its rotation and stop. The number and frequency of the pulses 2a are controlled to control the movement distance of a scanning body.

Filed: 1998-08-06
Abstract: PROBLEM TO BE SOLVED: To provide a vacuum cleaner which can control its operation appropriately according to the surrounding condition by detecting the volume of noise around the cleaner and controlling an electric fan according to the detected volume of noise. SOLUTION: The volume of noise around this vacuum cleaner is calculated based on the volume of noise detected by a sound detecting means 13 and the noise data of the cleaner itself stored in a memory means 24. The phase of an electric fan of the cleaner is controlled by a control means 22 according to the volume of noise around the cleaner. For example, the input to the electric fan can be reduced when the volume of noise around the cleaner is small. On the other hand, when the volume of noise around the cleaner is relatively large, the input to the electric fan can be increased.

Abstract: PURPOSE:To elevate the guard ring breakdown voltage by a method wherein a slant-type P-N junction is built of a region with its insulating film selectively provided with a window and is surrounded with an areally specified ion- implanted second region with its thickness smaller than that of the ion implantation projection distance. CONSTITUTION:An insulating film 11 is formed on an InP layer 4', to be provided with a window 11'. A portion of the insulating film 11', a specified peripheral region 11'' surrounding the region 11', is caused to be of a thickness D that is thinner than the ion projection distance. Ions are implanted for the formation of a P type conductive impurity region 5', and a heat-resistant, protecting film 12 is formed, and then heat treatment is effected for activation whereby a slant-type junction 5' is formed, diffused deep with impurity. In this way, guard ring structures 5', 5'' are created at the same time. This ensures a high breakdown voltage for the guard rings, bringing about sufficient multiplication in the light-receiving region.
